Sample L-moment for Right-Tail Censoring by a Marking Variable

Description

Compute the sample L-moments for right-tail censored data set in which censored data values are identified by a marking variable.

Usage

lmomRCmark(x, rcmark=NULL, r=1, sort=TRUE)

Arguments

x	A vector of data values.
rcmark	The right-tail censoring (upper) marking variable for unknown threshold: 1 is uncensored, 0 is censored.
r	The L-moment order to return, default is the mean.
sort	Do the data need sorting? The availability of this option is to avoid unnecessary overhead of sorting on each call to this function by the primary higher-level function lmomsRCmark.

Value

An R list is returned.

lambdas	Vector of the L-moments. First element is \hat{\lambda}^{(0,0)}_1, second element is \hat{\lambda}^{(0,0)}_2, and so on.
ratios	Vector of the L-moment ratios. Second element is \hat{\tau}^{(0,0)}, third element is \hat{\tau}^{(0,0)}_3 and so on.
trim	Level of symmetrical trimming used in the computation, which will equal NULL if asymmetrical trimming was used.
leftrim	Level of left-tail trimming used in the computation.
rightrim	Level of right-tail trimming used in the computation.
source	An attribute identifying the computational source of the L-moments: “lmomsRCmark”.
